Barrier

I disagree with the fact that every waterway=ditch implies barrier=ditch, however the reverse is true (a ditch barrier implies a ditch). Can we change it?

In my opinion neither implies the other one (there may be small ditch that is not a barrier, there may be a dry ditch that is a barrier but not a waterway) Mateusz Konieczny (talk) 08:31, 18 December 2014 (UTC)

Both are distinctive. A waterway=ditch is for draining, a barrier=ditch for denying access. Neither implies the other. Perhaps barrier=ditch should be man_made=ditch/trench? --Jojo4u (talk) 20:40, 25 March 2015 (UTC)

For drainage and irrigation

In Asian countries, ditches are commonly used as minor irrigation channels from a larger canal or pond. How do we differentiate a ditch used for drainage from that used for irrigation? --Planemad/Talk 07:15, 13 April 2016 (UTC)
